There's only one kind of 6c33 so there's no mystery what I'm looking for. I need 4.

For the 6sn7's, I need 10 new or almost new Chinese make, ie Shuguang.

Let me know if you have what I need.

Try ten Shuguang Treasure CV-181's      But bring your Amex platinum

I'd be curious to know how you like the standard Shuguang 6sn7s.  I have some CV181s on order, but only one pair for amp drivers...

if you go to ebay, you can buy an octet of new 6c33c tubes for $140-$180 shipped.  a bit more per tube, if you only want four...

Still need 6SN7s?

What about RCA GTBs?

Parts connection has a specially built 6c33 tester, so they do a good job of matching and testing them.

I just dug out and tested (AT1000) some NOS matched pairs:

Sylvania GTB small base, angled plates
Sylvania GTA fat base, angled plates
CBS 5692 brown base JAN new in box

PM if interested

p.s. I also have some RCA nickel base and RCA GTB here.
